The matchmaking for ranked multiplayer works like this:

  • Get the 100 "oldest" (creation time) available matches matching these conditions:
    • Opponent's league has to be between your league - 1 and your league + 1
    • If opponent's league is different than yours: league score delta has to be lower than 200 points
  • Filter out (remove) matches matching these conditions:
    • The opponent has already been played in the last 5 minutes
  • If there are matches remaining after filtering:
    • Sort the remaining matches using these comparison rules:
      1. Prefer opponents in the closest league
      2. In case of equality: Prefer opponents using a different IP
      3. In case of equality: Prefer opponents never met or met the furthest in the past
        Opponents are considered equal, if they have been met in the last 10 minutes
      4. In case of equality: Prefer opponents with the lowest league score delta (compared to yours)
        Opponents are considered equal, if the league score delta is <= 10
      5. In case of equality: Prefer oldest match (creation time)
    • Take the first match of the sorted list and join it
  • If there are no matches remaining after filtering:
    • Pick a random map
    • Pick a random left/right side
    • Create a new match using these parameters

GFX47 could you provide the rules for freeplay multiplayer?
